1. What Glosa is
Glosa is a constructed international auxiliary language whose stated purpose is communication between people with different first languages — explicitly not the replacement of those languages.1
Its design is analytic, or isolating: lexical forms take no endings for gender, number, tense or part of speech. Grammatical relations are carried entirely by word order and separate function words.21
The lexicon is deliberately a posteriori, drawing heavily on Greek and Latin roots of the kind found in European scientific, medical and technical vocabulary.213 One caution worth stating plainly: the founders' claim that this makes the vocabulary globally familiar is a design rationale, not a tested empirical result across populations.
2. Where it came from
Lancelot Hogben published Interglossa: A Draft of an Auxiliary for a Democratic World Order in 1943, presenting it as an experimental auxiliary with isolating structure, controlled word order, and a lexicon built on internationally circulated scientific roots.3
The Glosa Education Organisation's own history reports that Ronald Clark found a copy of Interglossa around 1960, contacted Hogben, and was encouraged to develop the project; Wendy Ashby joined Clark in 1972.4
Glosa altered its precursor rather than simply reissuing it, so Interglossa and Glosa should be treated as related but distinct systems.
3. Word order
The Basic Reference recommends the sequence: subject (with its modifiers), negation, modal, main verb, indirect object, direct object — and states that subordinate clauses keep the same order.2
Because nothing is marked morphologically, this order is not stylistic preference but the actual grammar. Depart from it and the sentence loses its structure.
4. Nouns, number and numerals
u (also written u(n)) marks a singular noun phrase without distinguishing definite from indefinite — it covers both English 'a' and 'the'. plu marks more than one. Both can also serve as noun markers where the word's category would otherwise be unclear.12
Numerals precede the noun in cardinal use: tri feli 'three cats'. An ordinal-like construction places the numeral after the noun: u feli tri 'the third cat'.2
5. Pronouns
| Glosa | Meaning |
|---|---|
| mi | I (1sg) |
| tu | you (2sg) |
| fe | she (3sg feminine) |
| an | he (3sg masculine) |
| id | it (3sg inanimate) |
| na | we (1pl) |
| vi | you (2pl) |
| mu | they (3pl) |
There are no case-inflected forms — mi is both 'I' and 'me'. The reference also lists pe for an indefinite person, se for reflexive use, auto for self/own, and alelo for reciprocal meaning.2
6. Tense, mood and negation
Time and aspect are carried by preverbal particles: nu (now), pa (past), fu (future), du (continuing/progressive). Combinations such as nu pa, pa fu and fu pa are also listed.12
Modality uses separate preverbal items: pote (ability), posi (possibility), nece (necessity), debi (obligation), volu (wanting).2
Sentential negation is ne. The reference distinguishes this from the prefix no-, which forms a lexical opposite rather than negating the clause — the difference between 'not cold' and 'hot'.12
7. Questions
Yes/no questions are introduced by qe. Content questions are built around qo.2

Sources: 18 Steps to Fluency in Euro-Glosa1 and the Glosa Basic Reference.2
Mi pa visita u teatra and Mi fu lekto u bibli differ in one particle each. What do pa and fu do, and what does u do in both?
Show answer
pa marks past, fu marks future — both preverbal, with no change to the verb itself. u marks a singular noun phrase without distinguishing 'a' from 'the'.
Turn Fe ki ad urba ('She goes to town') into a yes/no question, and explain the mechanism.
Show answer
Qe fe ki ad urba? The particle qe is prefixed to the clause; word order is otherwise unchanged and no verb form is altered.
Glosa has both ne and no-. What is the difference?
Show answer
ne negates the sentence. no- is a prefix forming a lexical opposite — so 'not cold' (ne + cold) is not the same as the word meaning 'hot'.

Honest limitations
This is an orientation, not a course. Almost everything here rests on the project's own publications — 18 Steps, the Basic Reference and the Glosa Education Organisation's history — so the account of Glosa's design and origins is largely self-reported and has not been checked against independent scholarship. The sources give no modern corpus analysis of how productive or ambiguous the lexical-category flexibility actually is in use, so that design rule is reported as stated rather than as demonstrated. No speaker numbers are given: none could be sourced. The three exercises above are built from attested sentences and attested rules, but the questions themselves are editorial.
